Cyclone for air cleaning and filtering module having the same

Abstract

A filtering module includes a cyclone having a contaminated air inlet part into which external contaminated air and cleaning water cleaning the contaminated air are each introduced, and a cleaned air outlet part through which air cleaned by bringing the cleaning water into contact with the contaminated air is discharged; a water tank coupled to the cyclone, to which the cleaning water cleaning the contaminated air is introduced, and storing mixed water in which a pre-stored fluid and the cleaning water are mixed; and a fluid circulating part providing the mixed water stored in the water tank to the contaminated air inlet part.

What is claimed is: 
     
       1. An air filtering module comprising:
 a cyclone including:
 a contaminated air inlet part into which external contaminated air and cleaning water for cleaning the contaminated air are introduced; and 
 a cleaned air outlet part through which air is discharged after being cleaned by bringing the cleaning water into contact with the contaminated air; 
 
 a water tank coupled to the cyclone, the water tank being configured to receive the cleaning water from the cyclone, and to store the cleaning water; and 
 a fluid circulating part configured to provide the cleaning water stored in the water tank to the contaminated air inlet part, 
 wherein the fluid circulating part includes:
 a pump configured to supply the cleaning water stored in the water tank to the contaminated air inlet part; 
 a heater configured to increase a temperature of the cleaning water supplied by the pump, to thereby supply the cleaning water at an increased temperature to the contaminated air inlet part; 
 a connection pipe interconnecting the water tank, the pump, the heater, and the contaminated air inlet part; and 
 a temperature sensor configured to measure the temperature of the cleaning water which is supplied to the contaminated air inlet part, 
 
 wherein the cyclone further includes:
 a cylindrical body including the contaminated air inlet part and the cleaned air outlet part, the contaminated air inlet part and the cleaned air outlet part being in communication with one another; 
 a conical body extending from the cylindrical body in a downward direction of the cylindrical body; and 
 a discharging part extending from the conical body in a downward direction of the conical body, 
 
 wherein the contaminated air inlet part is located at an upper end portion of a side of the cylindrical body, the contaminated air inlet part being arranged so that the contaminated air is introduced in a sideward direction of the cylindrical body, 
 wherein the cleaned air outlet part is located at the upper end portion of the cylindrical body, the cleaned air outlet part being arranged so that the cleaned air is discharged in an axial direction of the cylindrical body, 
 wherein the cleaned air outlet part is disposed in a direction orthogonal to the contaminated air inlet part, 
 wherein a central axis of the cyclone is inclined at an inclined angle with respect to a surface of the cleaning water stored in the water tank, and 
 wherein the water tank includes:
 a groove part configured to receive a side of the cyclone and to support the cyclone at the inclined angle; and 
 a foreign material discharging part located at a position corresponding to the surface of the cleaning water stored in the water tank, the foreign material discharging part being openable and closable. 
 
 
     
     
       2. The air filtering module of  claim 1 , wherein the cleaned air outlet part includes an extension part extending below the cylindrical body, and
 wherein the cleaned air is discharged through the extension part. 
 
     
     
       3. The air filtering module of  claim 2 , wherein a lower end of the discharging part is located below a surface of the cleaning water stored in the water tank, and
 wherein the discharging part includes at least one discharging slit. 
 
     
     
       4. The air filtering module of  claim 1 , wherein the cleaning water comprises water mixed with a pre-stored fluid. 
     
     
       5. The air filtering module of  claim 1 ,
 wherein a lower end of the discharging part is located below a surface of the cleaning water stored in the water tank.
